SPECIFICATION forming part'of Letters Patent No. 665,674, dated January 8, 1901. Application filed April 23, 1900. Serial No. 13,879. (No model.)

To all whom it may concern:

Be it known that I, ALFRED GARTNER, a citizen of the United States, residing at 579 Broadway, in the city of Paterson, county of Passaic, and State of New Jersey, have invented certain new and'useful Improvements in Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in looms for weaving silk, cotton, or other fabrics, being especially applicable to ribbon or other narrow-Ware looms, and it relates particularly to that portion of the loom by means of which the weft or filler is carried through the shed formed by the warp-threads. Heretofore the weft-threadmetaining means, together with the weft thread, were moved through the shed either by means of suitablyconstructed shuttles or by means of needles. Looms embodying these constructions are well known as shuttle-looms and needlelooms, respectively. Shuttle-looms-and especial reference being made to ribbon-shuttle loomscontain many objectionable features. Besides requiring an increased power for operating the shuttles by means of intermediate rack-bars and pinions the shuttles are of such construction that only a limited and specified amount of weft-thread or filling material can be carried by the shuttles, and accordingly the loom has to be frequently stopped for the purpose of removing the empty quills or bobbins and replacing them by full ones. This frequent stopping of the loom causes delay and loss of time and besides is injurious to the mechanism of theloom, as will be manifest to those familiar with the art. The second class of looms above mentionedneedle-loomsalthough overcoming the one objectionable feature of frequently stopping the loom for the purpose of replacing empty quills or bobbins, does not in every respect answer the requirements of a perfect loom. First of all, through the peculiar construction the weft laid between the warp is doubled, and besides in most cases the edges of the fabric woven are imperfect that is to say, the loops formed by doubling the weftthread are merely held in position by means of the crossing warps, and thus the withdrawing of the Weft and the pulling apart of the finished fabric can easily be accomplished. Furthermore, the construction of a needlelooin is too delicate and requires constant re-' pair, which undoubtedly is one of the main obj ectionable features. Another class of looms may be mentioned-21 e., that in which the thread-carriers of the looms are engaged by propelling screws or Worms in portions of said carriers which are remote from the thread-receiving portions thereof. The objectionable features of this class of looms are apparent and are to a certain extent the same as those mentioned in connection with the ordinary shuttle-loom. In addition to those obj cations are added the imperfect action of the carriers and the cost of construction and of running, which, all in all, have rendered such looms impracticable for the trade, and accordingly the market for the same is very limited.

The object of the present invention is to overcome the various objectionable features of the three classes of looms above mentioned and to provide a loom simple and durable in construction, perfect in action, especially in so far as the carriers are concerned, efficient in operation, not liable to get out of order, easily operated, and permitting the use of bobbins, quills, or spools of almost any shape, size, or construction, whereby the necessity of stopping the loom for changing empty quills or bobbins is reduced to the minimum.

The invention consists in the improved loom, in the weft-thread carrier, in means for propelling said carrier, adapted to engage the sanie in the thread-receiving portion thereof, whereby the thread or filling surrounds the propelling means, and in the combination and arrangement of the various parts, substantiallyas will be hereinafter more fully described and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a side elevation of a loom provided with my improvements, only those parts of the loom being shown which are necessary to fully illustrate the nature of the said invention. Fig. 2 is an enlarged front elevation of a portion of the batten and of the weft-thread carrier audits operating and propelling means with certain portions shown in section; Fig. 3, an enlarged detail end elevation of the weft-thread carrier operating or propelling means; Fig. 4, a detail view of tlie weft-thread carrier detached and also showing one form of tension device capable of being used in connection with my improvements, and Fig. 5 an end elevation of Fig. 4.

In said drawings, it represents the loomframe, and Z) the maindriving-shaft, transmitting motion through crank and pitman c to the batten d, the latter being supported by lay-swords e, fulcru med on the shaftf, having bearings in the frame a, all of the usual and well-known construction.

On the batten d and at specified suitable intervals are secured brackets g and 9, forming bearings for the shafts h 71', arranged in alinement with each other and having secured thereon screws or worms iandt", respectively. It may be Well to remark that the grooves in the screws or worms iand 't" correspond in pitch or inclinethat is to say, the pitch of the screw or worm 2" forms a continuation of the pitch of the screw 1', for a purpose hereinafter stated. On one of the screws (in the drawings on the screw 7;) is loosely arranged a sleeve or carrier m, provided at its ends with inwardly-extending lugs or projections mm adapted to engage the grooves of the screws or worms *5 and '8. Said sleeve or carrier is provided in its lower portion with alongitudinally-extending groove or recess m preferably inwardly beveled, (see Fig. 5,) slidingly arranged on the guide plate or bar at or n, which latter are securedto their respective bracketsg and g in any desired manner. Said guide plate or bar prevents the rotation of the sleeve or carrier while the latter is being reciprocated, as will be manifest. The sleeve or carrier mis also provided at suitable places with recesses 0 0', in which are secured fiat springs o 0 carrying at their free ends upwardly-extending lugs or projections 0, adapted to retain upon the sleeve or carrier a spool or bobbin 19. It will be noticed that by means of the peculiar construction of said retaining means the spool or bobbin can be readily removed from and placed upon the sleeve or carrier and when so disposed will be prevented from lateral motion, at the same time being allowed to freely revolve on the latter.

Any suitable tension device can be arranged on the sleeve or carrier, and in Figs. 4 and 5 is illustrated oneform of tension device which can be quickly attached to or detached from the said carrier. Said tension device consists of an L-shaped bar or rod 0", havingits shorter arm 0" removably secured by means of ascrew r in a recess or groove arranged in one end of the carrier m. The free end r of the longer arm of said bar or rod 7' is bent inwardly at right angles, and to it is secured one end of a spiral spring 5, the other end of which carries an eyelet s. A similar spring 5 with an eyelet s is secured to the shorter arm 7', substantially in alinement with the spiral spring 3. The weftthread t passes through one of said eyelets to and through the other and then through an eyelet 8 arranged approximately in the central portion of the bar or arm r. On each of the shafts h and h is securely mounted a pinion u, meshing with a gear a, secured on a shaft M, which latter is parallel with the main driving-shaft and is supported by and extends longitudinally of the batten d. On one or both ends of said shaft n is mounted a pinion n. meshing with the toothed segment u, revolubly arranged on a stub-shaft if, having its hearings in brackets secured to and projecting from the batten d. The segment is provided with a radially-arranged arm n, pivotally connected, by means of a rodo', to a pin 1 which latter is eccentrically arranged on the pinion v revolubly mounted on the shaft f. Said pinion 12 receives an intermittent motion from the disk 10, which for this purpose is provided on its outer periphery with a toothed section w. The disk to is mounted on a shaft 10 which also carries a gear-wheel r0 receiving its motion from the gear-wheel w on the main driving-shaft b by means of an intermediate pinion w, revolubly mounted on a stub-shaft in, which latter has its bearings in the frame a, all as clearly shown in Fig. l of the drawings.

It should be remarked that the various motion-transmitting gears must be of such size and construction that when the main driving-shaft makes one complete revolution the shafts h and h are rotated sufficiently to propel the carrier mfrom its rest position on the screw 71 to its rest position on the screw i, or vice versa, thereupon permitting the shafts hand It to cease to rotate long enough for the changing of the sheds, as will be manifest.

I do not think it necessary to describe in detail the operation of weaving in connection with my improvements, as said operation is precisely the same as that of an ordinary shuttle-loom, the weft-carrier being propelled from one side of the shed, through the shed, to the other side, when it stops to allow the sheds to be changed, said weft-carrier being thereafter returned to its former position.

I have described my improvements in connection with the loom illustrated in the drawingsthat is to say, in connection with a narrow-Ware loom-only one section having been shown; but it will be manifest that the same principles can be applied to broadcloth-looms, and, in fact, to looms for weaving any kind of fabrics. I'may also state that the mechanism for oscillating or rotating the shafts h and h could be changed, and likewise the bobbin-retaining means and the carrier-guiding means could be altered, without deviating from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
